' WILLIAM BOTTOMLEY'KEIGHLEY, F VINELAND, NEW JERSEY.

To all whotrl it may concern: i

I "Be it "known that I, WILLIAM Bo'rToMLEY I KEIGHLEY, a citizen of the United States,

I and a resident of Vineland, New Jersey, have invented certain Imfprovements in whereby it is held to the. topo any of a numberof position's;;t he arrange-V.

Shoe-Trimming Machines, 0' whichjthe foli.This' invention relates to machines par: t cularly-deslgnedfor trimming surplus materlal from the edgesof the'w eltfliningetc,

' during the manufacture of shoes; one object I of the invention being to provide mechanism ends I secure as hereinafter set forth, refer ence-being had to the accompanying draw- 'of t'he machine shown in Fig. 1.

. that it will be a practical to get'out of order.

scribed in my Patent, #928,133, dated July which extends immediately -for use in connection with a band knife; whereby the work will'he properly support 3 ed and fed Ito-thc same so as to be cleanly'i cut; the arrangement of parts being such v I impossibility for the functions of the machine to be interfered. with the accumulation of'fine threads. etc. .I further desire toprovide a shoe trimming machine of a simple [and substantial construction which shall be capable of automatically' maintainingitself in adjustment, which may be easy to operate, and not likely' 'These objects and other advantaeous ings, in which constructed according to my invention; Firm. 2, 1s a plan; and, Fig. 3,-1s a front elevation In theabove drawings, 1 is a supporting post mounted upon the frame of a band knife machine such as'that shown and de- 13, 1909; the blade-of the knife being indi cated at 2, and the body of the post being at some distance back of said blade. its upper SHOE-TRIMMING MACHINE. J

'7 and 'has fixed totitT-a'wornirlfi part has a forwardly projecting, portion adjacent to the rear side of the knife and supports a sheet. metal guard 3 which passes around the front of the knife so as to cover the same. Said guard extends to the level of the top of the post 1 and has a transverse slot for the reception of the end 4 of an elongated work supporting plate 5 preferably made of spring material and provided with a relatively sharp edge at its upper end, where it bears-against. the front side of the knife 2. It is held in place by the guard 3, which in turn is confined to the forwardly projecting portion of the post by a screw 6. The'rear nient being such as. to permit-of its transverse adjustment relatively ,t0. tl1'e knife. The block 7 has on itstop a bearing 9 for a. short shaft or spindle 10 carrying.- a worm '65 wheel 11 and a conical toothed; cuttingwheel 12; a limited portion ot};.tl1e:base'q this cutter lying in engagement; with the beveled,

edge of the knife-2, as bestshown in 'lflg. 2.

Said knife thus I acts to" shear off the surplus material, while the action of the cutter 12 very effectually prevents any accumulation or clogging of cuttings or threads around the kni e.

The spring 13 maintains the cutter in engagement with the knife and as the latter wears, the block 7 and with it the cutter, may be adjusted sothat the knife and cutter are kept in the desired relative positions.
